g100num [7]

Answer:

The correct option is c) n=5.

Therefore the solution to

$3n+4=24-n$

is

$n=5$

Step-by-step explanation:

Given:

$3n+4=24-n$

To Find;

n = ?

Solution:

$3n+4=24-n$ ........Given

Add + n to both the side

$3n+4+ n=24-n+n\\4n+4=24$

Now Subtract 4 on both the side

$4n+4-4=24-4\\4n=20$

Dividing by 4 on both side

$\dfrac{4n}{4}=\dfrac{20}{4}\\\\n=5$

Therefore the solution to

$3n+4=24-n$

is

$n=5$

Dafna11 [192]

Answer:

The graph has a closed circle at 10

Step-by-step explanation:

Let

x ----> the number of rentals

The phrase "no more" means "less than or equal to"

so

The inequality that represent this situation is

$1.50x+10\leq 25$

solve for x

$1.50x\leq 25-10$

$1.50x\leq 10$

$x\leq 10$

The number 10 is included in the solution

therefore

The graph has a closed circle at 10
